Ventoxx Slim Line

by Ventoxx
  • Ventoxx system is designed for ventilation in residential buildings and apartments, office premises, educational institutions, including preschool ones, with a significant percentage (from 75 to 91%) of heat recovery provided by a ceramic heat accumulator of German production!
  • Often, up to 45% of heat loss of residential buildings in heating period falls on conventional ventilation system. At the same time, performance of such systems is not constant and depends on many variable factors, such as difference in temperature inside and outside the room, windiness, state of vent ducts, etc. With the use of mechanical ventilation, it is possible to provide necessary air exchange rate based on operating mode of room itself. Reventa system has several operating modes (speeds), each of which corresponds to one or another requirement. Reventa control has a built-in function allowing you to choose direction of air movement (flow/outflow) depending on needs. Speed of air flow in the room with the system switched on does not exceed 0.1 m/s. The overriding component of recuperator is a high-quality ceramic heat accumulator of German production, which, unlike metal or copper heat exchangers, provides maximum energy conversion efficiency of recovery in its class, up to 91%, which is confirmed by numerous tests of the device in a wide variety of conditions, as well as the German ERP certificate (Energy Lable). Energy conversion efficiency is not peak, the calculation includes the entire temperature drop of supply air. This principle of operation allows the system to operate without extra electrical heating of supply air at low temperatures (below -20 deg.). In a complex, all these indicators allow us to complete this recuperator model in energy-efficient houses, as well as in existing buildings. At the same time, the maximum effect from energy efficiency of the building structure is preserved.

Although every effort has been made to present correct and up to date data, EBRD does not accept responsibility for the accuracy of the data presented.

**Included technologies ‎have been assessed to result in at least a 20% higher energy performance than the market average

2. The savings are calculated for the refurbishment of an average dwelling or the replacement of an average equipment in Ukraine. The actual savings of individual refurbishment projects/equipment can differ from the indicated savings due to specific climatic conditions, size of the dwelling/equipment, consumer behaviour, etc. The displayed energy efficiency measures only have an impact on individual household's bills (savings) if there is consumption based billing available.

3. Even though we have taken reasonable care to apply up-to-date energy prices when calculating savings in UAH, we do not take responsibility for the accuracy of any savings estimates stated on this Site.

4. All prices displayed in our Technology Selector are provided by the suppliers as indicative retail prices and should be used for reference purposes only. The actual prices of the vendors/retailors can be different from those on our web site due to various reasons beyond the influence of IQ energy programme.
